Before you forecast, you will need to set up the Program Order, create Model Alternatives, assign Model Alternative Keys, and create at least one Forecast Run. You will also set the default time window for your forecast and ensure that data is available for your forecast. Remember, it is essential that you setup the program order, before forecasting.

MFP Model Alternative contains information on how to create MFP model alternatives. For the other software applications, refer to Model Alternatives and Forecast Runs and the individual user documentation (HEC-HMS, HEC-ResSim, HEC-RAS, and HEC-FIA).
